At present the police can give offenders who have committed certain offences a final warning, or a fine, rather than sending them to court. But the Government is considering introducing a conditional warning, which would allow a young person to avoid court if they agree to change their behaviour.
The Youth Courts Committee of the Magistrates' Association is concerned about the proposals, which it argues could pressure innocent young people to admit guilt to avoid a court appearance, and place too much power in the hands of the police.
John Fassenfelt, chair of the committee, said: "Giving more power to the Crown Prosecution Service and police is worrying for youth court magistrates. We are concerned for the loss of judicial independence."
The proposal is believed to cover relatively serious offences, including low-level assaults, and Fassenfelt said there is no guarantee that youth offending teams would be involved. He also said there is a possibility of awards being given to victims.
A second proposal gives police recognition for resolving minor incidents without arresting the offender. If the matter is resolved between the injured party and the offender the police would be able to get credit, without using legal powers.
The draft proposals are understood to have been approved by ministers, and more detailed versions are being scrutinised. Giving police more power would require legislation.
